Time-delay fuses are designed to handle brief inrush currents common in motor-loaded circuits without nuisance tripping, while still providing fast overcurrent protection when a true fault occurs. This fuse ships in a 4-pack configuration, making it a practical restocking option for electrical contractors and service technicians. It installs into standard Edison-base fuse sockets found in older residential load centers and fused disconnect boxes. Licensed electricians and HVAC technicians are the primary installers for this type of overcurrent protection device.\u003c\/p\u003e\n\u003cp\u003eType TL plug fuses are commonly used in residential electrical panels and fused service disconnects that have not been upgraded to breaker-style equipment. They are well-suited for branch circuits serving motor loads such as HVAC equipment, refrigeration units, pumps, and appliances where temporary inrush current would otherwise cause an instantaneous fuse to open unnecessarily. The time-delay characteristic makes TL fuses a direct fit for these motor-circuit applications while maintaining compliance with NEC overcurrent protection requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-amp rating with time-delay response for motor-load branch circuits\u003c\/li\u003e\n  \u003cli\u003eType TL plug fuse design fits standard Edison-base fuse sockets\u003c\/li\u003e\n  \u003cli\u003eTime-delay action tolerates motor inrush current without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003e4-pack quantity supports efficient restocking for service calls\u003c\/li\u003e\n  \u003cli\u003eBoxed packaging keeps fuses protected during transport and storage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for Type TL plug fuse positions in residential Edison-base fuse panels and fused disconnects requiring 20-amp time-delay overcurrent protection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a qualified electrician in accordance with the NEC and applicable local codes. Always shut off the main disconnect and verify the circuit is de-energized before removing or installing fuses. Do not replace a fuse with a higher amperage rating than the circuit wiring is sized to carry. Ensure the fuse socket threads and contacts are clean and free of corrosion before installing the new fuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 20 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: Type TL Plug Fuse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResponse Characteristic\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 4 fuses per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackaging\u003c\/strong\u003e: Boxed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TL-20PK4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BUSSMANN","offers":[{"title":"Default Title","offer_id":51558361137458,"sku":"TL-20PK4","price":125.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/43f4fcf9273fdac28c3e4aee8bcf394c.jpg?v=1786410206","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-tl-20pk4-type-tl-plug-fuse-20a-4-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
